She felt the warm flushes of desire begin to course through her again, and she began to relax. Tentatively, she let her weight down on him. Her eyes closed and her mouth opened as she uttered a soft moaning cry of wanton pleasure. The thick knob stretched her vaginal lips wider than they'd ever been stretched before, and then, with a sudden sliding motion, it was inside her, and her cuntal lips snapped snugly around the entire knob of his cockhead.

Melanie gave a sob of delight. Her constricted vagina was throbbing with rapture. The pain had been minimal; a mere aching which was quickly overwhelmed by the rush of exquisite pleasure that consumed her loins.

But she had only taken the tip of his dick inside her. The lascivious flames that were flickering in Melanie's belly were excruciating, and she had a burning desire to feel more and more of his huge log of flesh inside her hungry sex chasm.

She relaxed her entire lower body and gave a whimpering cry of quiescent desire, dropping her entire weight on his upright organ. For an instant, her tight, glove-like channel resisted the thick, turgid stem of his impossibly long sword.

Then, all at once, it stretched wide open, and Melanie's eyes bulged as she felt the unbelievably pleasurable sensation of having her entire bower of bliss crammed full of pulsating manmeat.

Jarvis' huge wedge sluiced up her slick, clinging tunnel and banged against her cervix, stretching it incredibly. Her spasming pussy lips clutched at the turgid base of his dick, and her buns were resting in her brother's lap.

Melanie sobbed in joy as she rested on top of him, savoring the sensation of having herself stuffed to the brim with a thick cock. Then, she tentatively began to move.

Jarvis was in seventh heaven. As the silken, furnace-hot sheath of her unviolated tunnel slid tightly around the bulging, vein-latticed shaft of his sensitized erection, hot fires of raging passion kindled in his lusty balls, and he gave a low moan of delight.
